SEAT-SPRING FOR WAGONS.

'EEPECIEICATION forming part of Letters Patent. No. 334,425, dated January 19, 1886.

Application filed June 29, 1885.

To all whom it may concern: 7

Be it known that I, FORMAN F. FOWLER,

of Wolcott, in the county of Wayne and State of New York, have invented certain Improve- 5 ments in Seat-Springs for Wagons, of which the following is a specification.

The aim of this invention is to provide a spring attachment which may be sold in the market,and readily adjusted by the purchaser 1 to any lumber-wagon or other wagon having bolster with stakes or equivalent upright arms, to sustain a wagon-body, or a seat in the absence of the body; and to this end it consists, essentially, in a plate provided witha coiled or 15 equivalent sustaining-spring, and with adjustable guides to engage the stake.

Referring to the drawings, Figure 1 represents a bottom plan view of a seat provided with my attachments. Fig. 2 is a vertical 2O longitudinal section of the same. Fig. 3 is a crosssection on the line 31y. Fig. 4 is a top plan view showing the base-plate with adjust' able devices for connection to the bolster.

In the drawings, Arepresents a plate,which 25 may be of any appropriate form adapted to be screwed or otherwise secured to the under side of a wagon seat or board.

B is a spiral spring, secured at the upper end to the top plate and at the foot to a base- 0 plate, C, designed to be secured to the bolster. The top plate is provided with a notch or opening to admit the stake by which it is guided, and with three guide-plates, a, slotted and secured in place by bolts, so that they 5 may be adjusted to suit the size of the stake embraced between them. The inner ends of the plates are preferably provided, as shown, with rollers d, to act against the stake and thus reduce the wear and friction. The base Serial No. 170,161. (No model.)

plate is provided, as shown, with arms 6, se- 0 cured in place by bolts, so that when the plate is seated in position on the bolster the arms or clamps may be adjusted to embrace its sides and hold the plate in place, as shown.

In making use of the device it is secured 5 one to each end of the seat or a cross-board to sustain the wagonbody, and the whole placed in position on the wagon, the stakes being pointed to pass between the rolls and the baseplate secured to the bolster, as shown. 0

Having thus described my invention,what I claim isl. The spring attachment for wagons, consisting of the spring, the top plate secured thereto, the guides adjustably secured to the 5 plate, and the base-plate provided with ad justable devices for attachment to the bolster.

2. In a spring attachment for use on existing wagons, a spring,in combination with a top plate secured thereto, and the horizontally-ad- 6o justable guide-rolls secured to the plate,whereby the guides may be adjusted to standards of different sizes.

3. In combination with a seat-sustaining spring, a base-plate adjusted to extend across 6 5 the top of the bolster and provided with arms to clasp the two sides of the same, and a top plate recessed to admit the standard,said members constituting, jointly, a spring attachment applicable to wagons of ordinary con- 70 struction.

In testimony whereof I have hereunto set my hand, this 16th day of May, 1885, in the presence of two attesting witnesses.
